Description

Disposable environmental protection tableware and manufacture craft

Technical field

The present invention actual a kind of main be the disposable environmental protection tableware and the method for making of basic material with the vegetable fibre, relate in particular to recyclable, high-fall separating, free of contamination disposable environmental protection tableware.

Background technology

Current, the consumption disposable tableware that some restaurant units of China are a large amount of, the tableware that has is a plastic product, for environmental protection, the tableware that has is made of paper, what have is that raw material is made with timber, especially do raw material with timber, annual according to statistics about 160 ten thousand steres of consumption timber that need, the speed of falling trees is higher than the speed of growth of green wood far away, and a large amount of trees one go to pot, then the several years is difficult to recover, and China's timber resources and ecology environment is brought very big destruction, for this reason, the Chinese government has prohibited and has used wooden disposable tableware, these rules to begin in some areas to carry out.But what material to replace timber with? certainly, should adopt wide material sources, cost is low, easily degraded can not cause the destruction to resource, the simple material of manufacturing process, this material can meet recent and long-range needs, therefore, has been the task of top priority with this class material manufacture disposable tableware.

Summary of the invention

According to background technology, the object of the present invention is to provide a kind of raw MAT'L source wide, easily degraded is pollution-free, and the simple vegetable fibre of manufacture craft is for making the basic material of disposable tableware, its production process does not have " three wastes ", antiseptic property is good, and is not aging, can become fertilizer after the degraded, also can be directly as feed, make tableware with such base material and replace the disposable tableware made with other materials.

Another object of the present invention provides the manufacture craft of making disposable tableware at such vegetable fibre.

To achieve these goals, the present invention is achieved through the following technical solutions:

With vegetable fibre (straw, husk, corn maize, bagasse, the bamboo powder, peanut shell etc.) clear up (remove silt, remove rotten thing), be ground into powder, add starch in proportion, bonding powder stirs, and the vegetable fibre mixed powder that mixes up is tableware through heat pressing forming machines is hot-forming, packs after the finishing sterilization.

The present invention makes (consumption is a weight portion) by following component:

Vegetable fibre 40%-60%

Starch 15%-30%

Resin bond powder 25%-40%

Water 5%-10%

The manufacture craft that the present invention makes disposable environmental protection tableware by above-mentioned each component is:

1, gets vegetable fibre (straw, husk, corn stalk, bagasse, peanut shell etc.) earlier and clear up, remove rotten thing except that silt;

2, the vegetable fibre after will clearing up is that major ingredient is pulverized, and becomes 40-80 purpose fine powder;

3, add starch by weight proportion, water, resin bond powder stir (generally needing 20 minutes) and are modulated into the vegetable fibre mixed powder;

4, with the vegetable fibre mixed powder that modulates, determine into mould quantitative by the tableware capacity, hot moulding in heat pressing forming machines, after compacting reached pressure, venting was pressurizeed and was made product in 20 seconds rapidly, press product weight decision hot pressing time, heating and temperature control is used different moulds 125 ℃-143 ℃ (general patrix is controlled at 130 ℃, and counterdie is controlled at 128 ℃) instead according to different products on heat pressing forming machines;

5, manufactured product is repaired, approved product is paused finishing get final product;

6, manufactured product is carried out disinfection;

7, manufactured product is packed.

Owing to adopted technique scheme, the present invention to have the following advantages and effect:

1, the present invention's raw MAT'L wide material sources that can utilize, cost is low, and manufacturing process is simple, and production process does not have " three wastes ", and pollution-free is a good green product.

2, product of the present invention is after use, and starch wherein and vegetable fibre be in suitable temperature, under the damp condition, is subjected to action of microorganisms and decomposes, and makes the tableware degraded broken, becomes the fertilizer in the soil, and bonding powder is decomposed into alleviation fertilizer gradually.

3, the present invention can make all kinds of required disposable environmental protection tablewares by the difformity mould on the heat pressing forming machines.

The specific embodiment

Prescription main component of the present invention is a vegetable fibre (straw, husk, corn stalk, bagasse, peanut shell etc.), generally account for 40%-60%, after cleaning, be ground into 40-80 purpose fine powder, add starch or corn flour, wheat flour etc. in proportion and mix stirring with vegetable fibre with resin bond powder (commercial amino molding powder), in order to solve the flowing power of material, under stirring state, evenly in puddle mixer, evenly execute water sometimes.

Main process of the present invention is a high temperature, under the high pressure with starch (or corn flour, wheat flour), resin bond powder and vegetable fibre are blended in the new net structure of formation in the mould, wherein the resin bond powder plays waterproof and oilproof and fixation, the amount of resin bond powder can require quantitatively according to tableware, can add the water lubricate in the technological process, prevent the product distortion.

One embodiment of the present of invention are made (consumption is a weight portion) by following component:

1, during the system tableware

Corn straw powder 50%, corn flour 20%,

Amino molding powder 25%, water 5%.

2, the chopstick production period of the day from 11 p.m. to 1 a.m

Wheat straw bar powder 40%-60%, wheat flour 19%-20%,

Amino molding powder 25%-40%, water 2-10%.

By Fig. 1 the diagram of circuit of disposable environmental protection tableware manufacture craft of the present invention is shown, it is the processing technology of major ingredient that such technological process adapts to fully with the vegetable fibre, and is less expensive, than the actv. technological process.

Illustrate and the corresponding process equipment scheme drawing of technological process flow process shown in Figure 1 by Fig. 2, from scheming as seen hot-forming is the critical process of technological process, adopt the higher environment-friendly type heat pressing forming machines of degree of automation in order to improve the quality of products with capacity rating, this machine should have split type hydraulic efficiency pressure system and electrically controlled manipulation system, adopt the mold heated mode to work, heating-up temperature can be come automatic guidance by digital display temperature indication adjusting apparatus, double-type auxiliary cylinders speed accelerating circuits is set, make the make-up machine mold closing rapidly and balance, complete machine should be easy and simple to handle, and is safe and reliable.
